SPECIFICATION forming part of Letters'IPatent No; 720,120, dated February 10, 1903.

Application filed May 16, 1 901.

To all whom it may concern.-

Be it known that I,Go'rTL1EB;D. ELoEs-,a citizen of the United States of America; andra resident of Monticello,- in the county of Jones and State of Iowa, have invented certainnew and usefulImprovementsinwindow screens; and I do declare the following specification, taken in connection with the drawings mak ing a part of the same, to be a full, clear, and exact description thereof.

My invention relates to window=screens inwhich mosquito-netting-is stretched and secured upon a frame and the frame is mounted in the window-frame adjacent to thewindows 5* and it has for its object the construction of a window-screen which may be sustained in, place by means of a spring or elastic con nection between the screen-frame and the window-frame.

A further object is to allow the upper por tion of the window-screen to be pressed outward by the hand and when the pressure is spring or elastic pressure, to be automatically: drawn back to its normal position A further object is to mountthewindowscreen in the window-frame in suchfa way that an opening may be provided atithe top thereof, the lower edge remaining in place upon the window-frame, so as to' allow flies and other insects to escape through said open-.

It is well known that flies when disturbed usually fly upward, and hence the advantage; of being able to provide an opening at the top of the screen by simply pressing against the screen from theinside will'be' apparent;

In the drawings, Figure 1 is a perspective View of a window frame'and sill and of a Window-screen mounted therein and connected thereto by the spring device constituting a part of my invention. Fig. 2 shows a modification of the spring device for operatively connecting thescree'n and window frame.

Referring to the drawings, in which like parts are designated by thesame letters, A' represents thewindow-frame.

B, B, and B are the usual guide-strips. O is the base or sill of the window-frame. D is the screen-sash. The'u'sual method of operatively securing the screen in the window has been to fasten {curled end over said pin. stood thata like spring and fastening means serial No 60,5 '78 -(No moclel.)

Its lower end maybe secured to the side pieces of the screen-sash by means of a screw or pin J, passing through a slot K in said spring. The upper portion of said spring is curled away from the screen-sash and may be socured tothe strip B" bya pin or screw L. It will be understood that one of the spring devices'may be secured at either. side of the window-frame-and screen-sash. It will now be seen that the screen will be held in place against the weather-strip B and base of the window-frame by the tension of the springs By pressing against the screen with the hand'at any point above the springs the upper portion thereof may be moved away from the weather-strips, allowing flies and'insects to escape through the space so formed. As soon as the hand-pressure is released, the springs will draw the screen back to its normal position against the weather-strips.

The modifications here shown will operate in all respects the same, and other forms of springs will readily suggest themselves to the skilled mechanic which wouldnot be a departure from the scope of my modification.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1.
